What is Universal Gravitation?

Back

Universal Gravitation is a fundamental principle stating that every mass attracts every other mass in the universe, with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

What is the formula for gravitational force?

Back

The formula for gravitational force (F) is F = G * (m1 * m2) / r^2, where G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers.

What is the value of the gravitational constant (G)?

Back

The gravitational constant (G) is approximately 6.674 x 10^-11 N(m/kg)^2.

What does 'g' represent in physics?

Back

'g' represents the acceleration due to gravity, which is approximately 9.81 m/s² on the surface of the Earth.

Front

What is the direction of the gravitational field?

Back

The gravitational field is directed towards the center of the Earth.

Front

What is Kepler's First Law?

Back

Kepler's First Law states that planets move in elliptical orbits with the Sun at one of the foci.

Front

What is Kepler's Second Law?

Back

Kepler's Second Law states that a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time.

Front

What is Kepler's Third Law?

Back

Kepler's Third Law states that the square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit.

Front

What is the Orbital Radius?

Back

The Orbital Radius is the distance from the center of the Sun to the center of a planet.

Front

How does mass affect gravitational force?

Back

Gravitational force increases with the mass of the objects involved; larger masses result in a stronger gravitational attraction.
